How do rootstocks mediate scion salinity tolerance under salt stress?
Grafting in tomato has been investigated mainly in small-scale experiments, demonstrating morphological, physiological, and metabolic changes in the scion mediated by the rootstock. By grafting a scion onto different rootstocks, scion salt tolerance.....»»
Road Salt Works. But It"s Also Bad for the Environment.
As snowstorms sweep the East Coast of the United States this week, transportation officials have deployed a go-to solution for keeping winter roads clear: salt. From a report: But while pouring tons of salt on roads makes winter driving safer, it als.....»»
Data confirm link between respiratory stress and fish reproduction
A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active—and spawn for the first time—in response to growth-induced respiratory stress......»»
Modern humans developed a more effective protection against oxidative stress
Very few proteins in the body have adaptations that make them unique compared to the corresponding proteins in Neanderthals and apes. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden.....»»
The Goldilocks effect: Adding the right amount of sediment to salt marshes keeps coastlines afloat
Adding just the right amount of sediment to the surface of a Connecticut salt marsh protects coastlines by promoting rapid plant growth, scientists from the University of Connecticut report in a new study published recently in Environmental Engineeri.....»»
Contorted oceanic plate caused complex quake off New Zealand"s East Cape
Subduction zones, where a slab of oceanic plate is pushed beneath another tectonic plate down into the mantle, cause the world's largest and most destructive earthquakes. Reconstructing the geometry and stress conditions of the subducted slabs at sub.....»»
New grafting technique could combat the disease threatening Cavendish bananas
Scientists have found a novel way to combine two species of grass-like plant including banana, rice and wheat, using embryonic tissue from their seeds. The technique allows beneficial characteristics, such as disease resistance or stress tolerance, t.....»»
Study finds that not even the largest lakes in the world are safe from salt
Tourist towns along the Lake Michigan shoreline love to proclaim the giant body of water "Unsalted and Shark-Free." The slogan is plastered on t-shirts, magnets and bumper stickers—but, according to a new study, only one of those claims holds water.....»»

Use these setups and tips this holiday season to have your smart home ease any stress for you and your guests......»»
Meta-analysis of two types of molecular stresses reveals common factors
Stress can impact sleep, focus and more—down to our molecules. Oxidative stress results from an imbalance of oxidants and antioxidants, caused by an increase of free radicals, or reactive oxygen species, that can damage cells and their components......»»
Earth"s early oceans may have been heavy on the salt
Yale scientists say Earth's ancient oceans likely were much saltier than they are today—a finding that may spice up our understanding of how life, atmosphere, and climate evolved on the planet......»»
Smoke, heat and stress: A snapshot from Southern California of life in an altered climate
From record-breaking heat waves to massive wildfires, floods and long-running drought, the impacts of climate change across the U.S. have been impossible to ignore in 2021. While conditions vary from one region to another, it is clear that no part of.....»»
Researchers enhance thermoelectric performance of SnTe
Thermoelectric material (TE) realizes the conversion of electricity from waste heat. Since SnTe contains toxic-free elements and possesses the high-symmetry rock salt crystal structure, it has gained much attention in the thermoelectric field. Howeve.....»»
Tropical fish… up north? How ocean physics alters water temperature and salinity
A study led by Woods Hole Oceanographic Institution scientists is explaining why warm and salty water along with warm water fish species, such as the deep-sea dwelling Gulf Stream flounder and Black Sea bass, were found far inshore in New England in.....»»
DNA transcription speeds, a function of collective modes driven by DNA supercoiling
A team of physicists working at the intersection of theory and experiment are shedding new light on the 'teamwork' of molecular motors -- called RNA polymerases (RNAPs) -- that mediate DNA transcription. The researchers' work revealed for the first t.....»»
MSI is allegedly dropping the price of some RTX 3000-series cards
The claim comes from the Board Channels forum (via VideoCardz), which has proved reliable on previous occasions but should still be taken with a healthy dose of salt. According to the machine-translated post, the MSI graphics card factory has adjuste.....»»
DNA transcription speeds, a function of collective modes driven by DNA supercoiling
A team of physicists working at the intersection of theory and experiment are shedding new light on the "teamwork" of molecular motors—called RNA polymerases (RNAPs)—that mediate DNA transcription. During transcription, the first step in gene exp.....»»
Spaceflight wreaks havoc on liver metabolism
Researchers have demonstrated that microgravity and other environmental factors in space play different roles in inducing oxidative stress, which, in turn, alters the metabolism of sulfur-containing compounds in the liver of mice. The study highlight.....»»
Stress makes life’s clock tick faster: Chilling out slows it down
Scientists in recent years have developed ways to measure biological age by tracking chemical changes in DNA that occur naturally as people age but occur at different times in different people. These so-called 'epigenetic clocks' have proved to be be.....»»
Research reveals how aging cells can be an underlying cause of kidney damage
A study in mice has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and.....»»
Preventing extreme polarization of political attitudes
Encouraging interactions between people on opposite ends of the political spectrum may not be the best way to foster tolerance in a polarized nation......»»
